Is it true that using makeup with SPF is just like wearing regular facial sunscreen?

FALSE. Certainly, applying makeup that contains SPF is better than skipping it altogether, but it's not as effective as wearing a facial lotion with sunscreen underneath. Generally, most makeup cracks on skin, allowing UV rays through. "For makeup to provide adequate ultraviolet protection, it would need to be applied in a really thick layer, which most women do not do," Jordana Gilman, MD, a New York City dermatologist, says. So unless you plan to spackle on your foundation, apply a layer of lotion with sunscreen first, and then apply your makeup.
